The continuous phase of this formulation exhibited streaming birefringence. An embodiment of a pesticide composition may include one or more active ingredients and one or more surfactants with the final formulation exhibiting streaming birefringence. Formulations may be in the form of solids e. It is to be understood that the surfactant adjuvants may include any one or combination of surfactants. It is to be understood that other pesticidal active ingredients may be formulated into a streaming birefringent phase.
The novel surfactant composition, pesticide composition containing the preparation and said surfactant composition. This application is a continuation of U. Furthermore, of the formulations that exhibited streaming birefringence, Formulations were brighter to the eye than the others. In some embodiments, the active ingredients comprise glyphosate, one or more salts thereof, or combinations thereof.
Active ingredients include herbicides such as glyphosate. The pesticide composition may contain any surfactant adjuvant suitable for providing streaming birefringence. Some manufacturers do not follow these industry standards, which can cause confusion for users.
It should also be realized by those skilled in the art that such equivalent constructions do not depart from the spirit and scope of the invention as set forth in the appended claims. Thus active ingredients may be formulated in a new thermodynamic equilibrium phase.
Following the manufacture of a pesticide technical material active ingredient, a. Formulations Formulation science Pharmaceutical formulation Galenic formulation. An example of a typical adjuvant is a surfactant.
Very occasionally, some pesticides e. In other words, the index of refraction changes with direction. At rest, a pesticide composition having streaming birefringence is isotropic and dark. Without limitation, examples of suitable oil-based adjuvants include crop oils, crop oil concentrates, vegetable oils, modified vegetable oils, or combinations thereof.
Further advantages include the elongated micelles of the pesticide composition showing that the system is very close to a hexagonal liquid crystal phase transition. Potassium glyphosate may be obtained from Monsanto St.
Both surfactants were obtained from Huntsman The Woodlands, Tex. One example is a phosphate ester of a tallow amine ethoxylate, although embodiments are not limited thereto. When flow is induced, however, the elongated micelles align themselves with the flow field to create a structured liquid system. In an embodiment, a pesticide composition includes a super high load mixed salt glyphosate soluble liquid formulation.
Pesticidal composition containing as surfactant viscoelastic agent and drift control method to improve adverse results in a pesticidal composition. During a project to investigate the maximum loading possible for a soluble liquid glyphosate formulation, a composition was discovered that exhibited streaming birefringence. Formulations improves the properties of a chemical for handling, storage, application and may substantially influence effectiveness and safety. The Pesticide Manual, which are each incorporated herein by reference in their entirety.
It is to be understood that streaming birefringence e. This average was compared to the average growth of that weed type in the control plots. In an embodiment, the active ingredients are dispersed in an aqueous medium by any suitable means. Integrated Pest Management Index of pesticide articles Pesticide categories.
Every effort has been made to ensure that hyperlinks are active. This invention relates to the field of pesticide formulations and more specifically to pesticide formulations that exhibit streaming birefringence.
In an embodiment, escribir pdf online the pesticide composition does not contain an inert adjuvant. Pesticide products very rarely consist of pure technical material. Pesticide formulations may contain one or more active ingredients and come in many different variations depending on the nature of the active ingredient and the proposed use. Formulations were also examined to see if they exhibited streaming birefringence.
In fact, it separated into two phases and it was turbid. In an embodiment, the adjuvants include an oil-based adjuvant. The presence of a liquid crystal phase provides many advantages to a pesticide formulation.
Cloud point was determined by mixing each formulation while heating until it became cloudy. Metolachlor may be obtained from Syngenta Greensboro, N.
Please help improve this article by adding citations to reliable sources. In addition, embodiments include the active ingredients including a fungicide. In some embodiments, the active ingredients include an insecticide.
It is intended that the appended claims cover all such modifications and variations as fall within the true spirit and scope of this present invention. Assay for selecting compositions providing enhanced effectiveness of exogenous chemicals applied to plants.
Thus, the sample is dark when placed between cross-polarized plates. Generally, the results were obtained by observing the growth of weeds on each plot and averaging the observations for the three test plots that were sprayed with a particular herbicide. At rest, the pesticide composition is isotropic and does not exhibit birefringence because, in theory, the micelles are randomly oriented. Any oil-based adjuvant suitable for use in agrochemical applications may be used.
In addition, the elongated micelles may be formulated into formulation types other than soluble liquids. For instance, the active ingredients may be dispersed by stirring, mixing, blending, and the like. To further illustrate various illustrative embodiments of the present invention, the following examples are provided. Pesticide formulations may also come ready to use or require dilution before use. In an alternative embodiment, the pesticide composition contains additional adjuvants.
